I built 2.6.18 and booted into it with cpufreq.debug=3, and got not a squeak out of it. There's no cpufreq-related info in /var/log/messages at all. > And again as Dave > mentioned, try both acpi-cpufreq and speedstep-centrino drivers. I'm using the Fedora kernel config, which builds acpi-cpufreq as a module and speedstep-centrino built-in, but no joy. I'll try building the lot as modules, and see how that goes. Here's what's in my .config with the setup that prints nothing at all: CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_TABLE=y CONFIG_CPU_FREQ_DEBUG=y CONFIG_CPU_FREQ_STAT=m CONFIG_CPU_FREQ_STAT_DETAILS=y # CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=m CONFIG_CPU_FREQ_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_ONDEMAND=m CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m CONFIG_X86_POWERNOW_K8=y CONFIG_X86_POWERNOW_K8_ACPI=y CONFIG_X86_SPEEDSTEP_CENTRINO=y CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI=y CONFIG_X86_ACPI_CPUFREQ=m # CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set # CONFIG_X86_SPEEDSTEP_LIB is not set
